Start with a Trapeze.
Swing the yo-yo back off and use your non-throwhand middle
finger to hold onto the string. Bring it all the way around your throwhand
wrist and land onto both strings.

As the yo-yo comes down on
the string, let go of it with your non-throwhand middle finger, and
circle around the yo-yo with your throwhand holding onto the string.
On the second pass, just as in Iron Whip help guide the string down
and in towards the gap of the yo-yo. Note:It is important to do this in one motion to keep
up the momentum of the string spinning around the yo-yo.
